This problem is called "thread galling." According to the Industrial Fastener Institute's 6th Edition Standards Book (page B-28), Thread galling seems to be the most prevalent with fasteners made of stainless steel, aluminum, titanium, and other alloys which self-generate an oxide surface film for corrosion protection.

Galling is a failure mechanism caused by two metal surfaces of similar chemical composition or surface hardness. As the surface undergoes load, galling results in a cold welding type of failure that causes the two surfaces to stick together.
